Dear Rodger,

Are you sure that it is really the double FOR loop that is slowing you
down?

I am building a framework for processing satellite time-series data,
which is similar to what you are doing here: looping over the rows and
columns and fitting a model to the data. I use Craig's MPFitFun to
fit a model (usually more complex then a polynomial), but I find that
typically 95% of the processing time is spent within the MpFit
routines. So trying to optimize on the double FOR loop will not gain
anything.

I suggest you run the IDL profiler on your code (maybe you did, but it
is not mentioned in your post) to see what is causing the delay.
